Exploring Biomarkers in Hereditary Transthyretin Amyloidosis

Hereditary Transthyretin Amyloidosis

Hereditary transthyretin amyloidosis (ATTRv, v for variant) is a severe and heterogeneous systemic condition due to mutations in the transthyretin (TTR) gene. The availability of disease-modifying therapies has led to an urgent need to have reliable biomarkers capable of assessing the clinical severity of the disease and of monitoring the efficacy of pharmacological treatment. At the same time, early markers for the clinical onset of ATTRv amyloidosis in presymptomatic subjects are needed to enable earlier initiation of anti-amyloid therapy. In this project the investigators seek to achieve three main goals: to identify and validate disease severity biomarkers in symptomatic patients; to establish disease onset biomarkers of ATTRv amyloidosis in presymptomatic subjects; to explore new pathogenetic mechanisms underlying this multisystem disorder, such as mitochondrial dysfunction and immune response.

A Clinical Study to Characterize Adverse Events Occurring Within One Day of TEGSEDI Administration...

Hereditary Transthyretin Amyloidosis With Polyneuropthy

The objective of the study is to characterize adverse events (AEs) occurring within one day of TEGSEDI administration to adult patients with hATTR-PN overall and in individual patients with respect to time course of AE onset, vital sign changes, preventive measures, treatment required, risk factors, and subsequent adverse outcomes.

AmyloidosisHereditary1 more

The purpose of this study is to evaluate the efficacy and safety of vutrisiran (ALN-TTRSC02) in participants with hereditary transthyretin amyloidosis (hATTR amyloidosis). Participants will receive vutrisiran subcutaneous (SC) injection once every 3 months (q3M) or the reference comparator patisiran intravenous (IV) injection once every 3 weeks (q3w) during the 18 month Treatment Period. This study will use the placebo arm of the APOLLO study (NCT01960348) as an external comparator for the primary and most other efficacy endpoints during the 18 Month Treatment Period. Following the 18 Month Treatment Period, all participants will be randomized to receive vutrisiran SC injection once every 6 months (q6M) or q3M in the Randomized Treatment Extension (RTE) Period.

Prevalence and Prediction of ATTR in Ambulatory Patients With HFpEF

Transthyretin AmyloidosisHeart Failure3 more

Recent studies have shown that transthyretin amyloidosis (ATTR) can sometimes cause a type of heart failure where the pumping function of the heart is normal, also known as Heart Failure with Preserved Ejection Fraction (HFpEF) or diastolic heart failure. In this single center diagnostic study, we will evaluate for ATTR in patients with HFpEF in order to to determine how frequently this occurs and how we can predict which heart failure patients may have TTR amyloidosis. Our goal is to identify amyloidosis in heart failure patients earlier so that they can start treatment.

Evuzamitide as SPECT/CT Imaging Agent for Diagnosis of Transthyretin Amyloidosis

Transthyretin Amyloidosis

This is a single center, prospective cohort study that is evaluating the ability of 124I-evuzamitide PET scanning to: (1) identify extra-cardiac amyloid deposits in patients with ATTRwt-CA and the Val122Ile variant; (2) to detect cardiac TTR amyloidosis in subjects with heart failure, increased wall thickness but only grade 1 Tc99PYP scans who are not currently diagnosed with ATTR-CA; and (3) to detect cardiac ATTR in allele carriers of TTR variants (Phe64Leu, late onset Val30Met) that are associated with cardiac amyloidosis but have PYP scans not diagnostic of ATTR-CM. If 124I-evuzamitide PET scanning is shown to be valuable in any of these three cohorts, it would address critical unmet needs regarding the diagnosis and extent of disease in ATTR-CM. Consented eligible patients will undergo a single 124I-evuzamitide PET scan. Clinically available demographic, clinical and phenotypic data that is collected as part of routine clinical care will be used to characterize the type, severity, and stage of ATTR-CM.
